Since breakdown phenomena occur in the positive polarity, the breakdown mechanism explanations about AC voltage are related to the mechanism of positive impulse and direct voltage. It is needed to mention the breakdown mechanism to explain the abnormal case.
The first part is three-phase uncontrollable rectifier at bridge connection with LC filter (Figure 2(a)) which corrects alternating voltage [V.sub.source] of fixed frequency into direct voltage [V.sub.dc].
If we assume that the alternating voltage source is present instead of the direct voltage source which is placed before the switching unit, and the voltage of which is equal to the voltage of the direct voltage source during time period when the commutator is in a switched-off position, we will have the equivalent non-switched voltage source.
It can accept a direct voltage input signal, allowing it to be used with most voltage sensor signals.
In order to now determine the frequency of the oscillator using a direct voltage, one of the capacitors is re placed by a junction varactor.
Operators connect the LTD to their controller, computer, or multimeter and set the instrument for a direct voltage input.
[S.sub.41] = direct voltage transmission coefficient of the coupler
